This week, Ariana Grande confirmed she’ll be holing a benefit concert—stacked with an impressive lineup on guests—to raise money for the families and victims of the Manchester Arena terror attack.

UPDATE:

But in a devastatingly low blow, more than 10,000 people have falsely claimed they were at the arena at the time of the blast to get free tickets to Sunday’s concert.

According to Sky News, Ticketmaster put aside 14,200 free passes for people who attended last week’s concert. However, around 25,000 claimed they were at the performance.

"Sadly, over 10,000 unscrupulous applications have been made,” a Ticketmaster spokesman said. "We're working hard to get tickets direct to fans. We are cancelling tickets of those who are reselling wherever possible,” they added on Twitter.

Tickets to the One Love Manchester benefit sold out in just six minutes.

Performing alongside the singer is Katy Perry, Justin Bieber, Coldplay, Miley Cyrus, Pharrell, Usher, Take That and Niall Horan, with more big names reportedly to be added soon.

Free tickets will be offered to anyone who was at Ariana's Manchester Arena show on May 22nd, with all proceeds made from other ticket sales going straight to victims and families of the 22 people who lost their lives and 59 who were injured.

A Just Giving crowdfunding page which was set up for the same purpose has almost reached its £2 million goal, with celebrities like Ed Sheeran, Justin Timberlake and Eminem pledging their support and encouraging their fans to donate.
